Hello,
I have 2 bluetti generators AC200P and EB70.
I was charging the EB70 with a Dokio flexible panel but having less than 35V VOC I can’t use it with the Bluetti AC200P.
Having had enough of deploying the folding panel in front of my roof windows, I’ve just bought 1 revolt panel that are the right size for my roof end.
Small hitch: no matter what type of cable I use, this panel doesn’t work with either the EB70 or the AC200P,
I had taken care to buy a panel with a VOC above 35V (advice given by bluetti after-sales service) but I don’t know enough about solar energy to understand the problem.
The AC200P worked very well with a 450W panel on another site, so I don’t understand where it’s stuck?
I put the links to the Revolt panel purchased for the characteristics and also 2 bluetti,
Thank you in advance if anyone can shed some light on this problem. See you soon!

Hello. Here’s what’s happening with your 150 W Revolt panel (Voc 43.71 V, Vmp 38.72 V, Imp 3.87 A):
EB70 won’t accept it
The EB70’s MPPT only handles panels up to Voc 28 V and 200 W max. Your panel’s 43.7 V exceeds that, so it won’t charge.
Specs: Solar Input 200 W max., Voc 12–28 V, 8 A → see Bluetti EB70 manual: https://bluettipower.co.uk/products/bluetti-eb70-portable-power-station
AC200P is only a marginal fit
The AC200P needs a panel with Voc 35–150 V and up to 700 W. Your Voc sits just above 35 V, but in anything less than perfect sun it will dip below and refuse to charge.
Specs: Solar Input 700 W max., Voc 35–150 V, 12 A → see Bluetti AC200P details: https://www.bluettipower.eu/products/bluetti-ac200p-power-station
How to fix it
For the EB70: switch to a low-Voc panel (e.g. a 12 V/200 W unit with Voc ~22–27 V), or add a DC–DC buck/MPPT regulator to step down to 12–28 V.
For the AC200P: wire two of your 150 W Revolt panels in series. That doubles Voc to ~87 V and Vmp to ~77 V—comfortably within 35–150 V—and doubles your wattage, too.
Always use a proper MC4→DC adapter cable rated for solar, plugged firmly into the PV input.
Once the panel voltages match each unit’s window (and you’ve got the right cables), both stations will charge reliably—even in less-than-ideal sunlight.
Hi Vik, sorry for late answer and big thanks for your clear complete answer.
I still need your help because I know nearly nothing about solar.
on this photo above is it this a controler correct for the eb70 ? and a question remains_ to reach a controller like this I need a cable with mc4 on one side and nothing on the other side?so I plug the bare cable into the controller and mc4 to the pannel. And how do I go from the controller to the EB70 ? Cheers
